A video artist who uses YouTube clips, a print-maker and an artist who pairs spoken word with photography are among this year's Turner Prize nominees.

Duncan Campbell, James Richards, Ciara Phillips and Tris Vonna-Michell are on the shortlist for the prestigious and provocative contemporary art prize.

This year marks the 30th anniversary of the Turner Prize, and true to its non-conformist nature, there are unlikely to be any oil paintings or figurative sculptures on display at the 2014 exhibitionWill Gompertz, BBC arts editor

Between them, they employ audio, video, craft and design - but there are no traditional painters or sculptors.

The winner, who will receive £25,000, will be named on 1 December.

Tate Britain director Penelope Curtis, who chairs the jury, admitted this year's Turner nominees were "less well known" than in previous years.

"They are serious works, they have quite a political or social commitment," she said at Thursday's shortlist announcement.

"It's perhaps less fun but I hope that we can do the job in communicating why these works are important and have caught the imagination of many people over the last 12 months."

Lizzie Carey-Thomas, Tate Britain's curator of contemporary art, said the shortlist was "more accessible" than in past years.

"It's not art about art, it's art about the world and other subjects everybody has experience of and can relate to."

Internet impact

The nomination announcement said the four artists' methods "suggest the impact of the internet, cinema, TV and mobile technologies on a new generation of artists".

Curtis said they shared "a strong international presence and an ability to adapt, restage and reinterpret their own and others' works, very often working in a collaborative social context".

BBC News arts editor Will Gompertz suggested that the four all "make work that is in some way shape or form, a collage".

He said: "This year marks the 30th anniversary of the Turner Prize, and true to its non-conformist nature, there are unlikely to be any oil paintings or figurative sculptures on display at the 2014 exhibition."

The nominees are:

Duncan Campbell

Dublin-born, Glasgow-based Duncan Campbell is nominated for a video that was part of Scotland's entry in last year's Venice Biennale.

His film, It for Others, is a reflection on a remarkable historical documentary about African art made by the French filmmakers Chris Marker and Alain Resnais in 1953.

It also includes a stunning dance sequence created with choreographer Michael Clark.

Campbell studied at the Glasgow School of Art. The city has produced four of the last nine Turner Prize winners.

Ciara Phillips

She has been shortlisted for a two-month project at The Showroom gallery in north-west London, where she set up a temporary print studio and invited artists, designers, and local women's groups to produce new screen prints.

She also set up The Poster Club, a collective of like-minded artists, in Glasgow in 2010, and creates screenprints, textiles, photographs and wall paintings.

The Scotsman wrote last year: "Phillips is a brilliant print maker who imbues the medium with a freshness that is remarkable, in posters, prints and textiles."

James Richards

James Richards pieces together apparently unrelated clips from a wide variety of sources - including YouTube, VHS tapes from charity shops, other artists' films and footage he has shot himself.

In one video, the Cardiff-born artist spliced together a clip of Heather Langenkamp in Nightmare on Elm Street with a girl drawing an eye in an instructional video and footage of space, all of which shared the same zoom speed.

He has been shortlisted for a 13-minute black-and-white video that was part of a group show at the Venice Biennale.

The Turner Prize citation said he created "poetic meditations on the pleasure, sensuality and the voyeurism that is within the act of looking".
